DOOR-FASTENER- Specification of Letters Patent.

To 107/- mimm if may concern.-

Be it known that we, JOHN W DICKSON and STEPHEN J. ELY, citizens of the United States, residing at Oasllerock, in the county of Cowlitz and State of \Vashington, have invented certain new and useful Improvements in Door- Fasteners; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in door-fasteners.

The object of the invention is to provide a device of this character whereby a door may be securely fastened or locked on the inside.

A further object is to provide a fastening device for doors which may be quickly and easily applied to the same and which when not in use may be easily carried about by the person possessing the same, said fastening being simple, strong, durable, and light in construction, efficient in use, and well adapted to the purpose for which it is designed.

W'ith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a horizontal sectional view through a portion of a door and the door-jamb, showing the application of the invention. Fig. 2 is a detail perspective view of the fastening removed from the door. Fig. 8 is a side elevation, partly in section. Fig. 4: is a transverse sectional view taken through the adjustable stop and the locking-pin arranged therein, and Fig. 5 is a detail view of the locking-pin removed from the stop.

Referring more particularly to the draw- .ings, 1 denotes the fastener, which consists of a bar or plate 2, one end of which is bent at right angles and provided with teeth or prongs 3. On one edge of the plate or bar 2 is formed a series of ratchet-teeth 4. In the end of the plate opposite to that having the teeth or prongs 3 may be formed an aperture or eye 5, by which the fastener may be hung upon a nail or hook.

Slidably mounted upon the plate or bar 2 is a stop 6, said stop being preferably in the form of arectangular block one end of which is provided with an offset or enlargement 7. In the stop 6 is formed a longitudinally-disdoor.

posed slot or aperture 8, through which the plate or bar 2 is adapted to pass. In the stop 6 is also formed a transversely-disposed aperture 9, which intersects the slot 8. Inthe aperture 9 is slidably mounted a locking-pin or bolt 10, in which is formed a vertically-disposed slot 12, the upper wall of which is inclined to form a tooth 13.

The plate or bar 2 is adapted to pass through the slot 12 of the pin or bolt, the teeth 4 on said plate being engaged by the tooth 13, formed in the slot 12 of said bolt. On one end of the pin or bolt 10 is formed a head 14:, between which and the adjacent side of the stop 6 is arranged a coil spring 15. One end of said spring 15 is connected to the head of the bolt, while the opposite end of the same is connected to the side of the stop 6, the tendency of the spring being to normally hold the pin or bolt 10 in a retracted position to engage the tooth 13 thereon with the ratchetteeth 4 of the plate or bar 2, thus permitting the stop 6 to be adj ustably secured to said plate or bar.

In applying the device to a door the plate or bar 2 is arranged between the edge of the door and the adjacent side of the door-jamb, the teeth or prongs 8 on the end of the plate being forced into the jamb, as shown in Fig. l of the drawings. After the plate 2 has been so arranged and the doorclosed the stop 6 is slipped onto the inner end of the plate and forced upwardly into engagement with the In forcing the stop 6 against the side of the door the teeth 13 on the locking-bolt will slide loosely over the ratchet-teeth 1 of the bar until said stop has been brought to the 'properposition. The engagement of the tooth 13 with the ratchet-teeth 4 will prevent the stop from being moved in the opposite direction until said tooth has been disengaged from the ratchet-teeth by the shifting of the locking-bolt, as will be clearly understood, thus holding the door in closed position.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. 7

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The herein-described doorfastener,oonsisting of a plate or bar having formed on one end right-angularly-projecting teeth or prongs and on one edge a series of ratchet-teeth, a

slotted block adjustably mounted on said plate or bar to form a stop, a pin or bar slidably mounted in said block, and provided With a slot through which the plate or bar passes, a tooth or pawl formed in the slot of said pin to engage the ratchet-teeth on said plate or bar nesses.
